*** WHAT'S COVERED ***
1. The concept of yield in chemical reactions.
* The difference between the actual yield (the amount of product you actually get) and the theoretical yield (the amount of product you expect based on calculations).
2. Reasons why the actual yield is often less than the theoretical yield.
* Incomplete reactions, which can occur if a reaction is slow or reversible.
* The occurrence of unwanted side reactions, which consume reactants to make different products.
* The practical loss of product during experimental procedures like filtering or transferring substances.
3. How to calculate the percentage yield.
* The formula used for calculating percentage yield: (Actual Yield / Theoretical Yield) x 100.
* A worked example showing how to apply the formula.
